Course  Description    

This  course  is  the  first  semester  of  a  2-­‐course  sequence  in  Organic  Chemistry.  Organic  chemistry  is  a  graphical,  textual,   and   verbal   scientific   language,   and   an   active   field   of   study,   research,   and   scholarship.   Chemistry   231   is   a   non-­‐ mathematical,  logical,  problem-­‐solving  course.  It  focuses  on  the  structures,  functional  groups,  nomenclature,  properties,   reactivity,   reaction   mechanisms,   and   the   synthesis   of   fundamental   classes   of   organic   compounds.   Most   of   the   examples   presented   contain   underling   principles   and   concepts   that   are   applied   repeatedly   throughout   this   course   and   in   future   organic   chemistry,   biochemistry,   molecular   biology,   and   other   science   courses.   Some   practical   applications   of   organic   chemistry   to   biological   processes   (neuroscience,   metabolism,   pharmacology,   toxicology,   etc.)   and   everyday   life   (medicine,  materials,  household  products,  food  science,  etc.)  will  be  presented  from  the  perspective  of  course  learning   objectives.  Due  to  the  nature  of  the  science  covered,  this  course  requires  oodles  of  drawing.  Consequently,  to  obtain  full   credit,  all  correct  answers  on  quizzes  and  exams  must  include  both  drawings  and  key  words.        

Course  Organization      

This  is  a  blended  lecture,  laboratory,  and  online  course  in  which  new  topics  are  first  presented  using  a  variety  of  formats   including:  assigned  textbook  readings,  our  D2L  course  website,  the  WileyPlus  online  homework  system,  in  lecture,  or  in   laboratory.  Our  scheduled  class  lecture  periods  will  be  used  for  a  combination  of  introducing  new  topics,  reviewing  key   concepts,  and  demonstrating  the  application  of  new  content  through  problem  solving  examples.  The  first  week  of  this   course  is  a  partial  review  of  selected  general  chemistry  concepts  invaluable  in  your  study  of  organic  chemistry  (Chapter   1).  Then,  organic  structures,  functional  groups,  and  acid-­‐base  chemistry  will  be  explored  in  the  context  of  fundamental   organic   chemistry   as   we   quickly   move   through   Chapters   2   and   3.   The   remainder   of   the   course   is   organized   by   functional   groups,  molecular  structure,  and  chemical  reaction  mechanisms.  This  course  is  fast  paced,  continually  builds  on  what  is   learned  in  the  first  month,  and  is  cumulative  by  nature.        

Course  Learning  Objectives   Upon  your  successful  completion  of  Chemistry  231,  you  will  be  able  to…   1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

Recognize,  name,  and  represent  (draw)  organic  compounds  and  organic  functional  groups   Estimate  the  attractive  forces  within  and  between  molecules   Analyze  structural  and  stereochemical  conformations,  configurations,  and  isomers   Compare  the  stability  of  organic  molecules  based  on  energy  considerations   Describe  relationships  between  molecular  structure,  chemical  reactivity,  and  physical  properties   Understand  how  and  why  organic  compounds  react  the  way  they  do   Apply  your  knowledge  of  acid  and  base  reactions  to  analyze  common  organic  reactions   Predict  products,  starting  materials,  and/or  reagents  based  on  functional  groups  as  sites  of  reactivity   Propose  and  defend  mechanisms  of  elementary  reaction  electron  flow  using  curved-­‐arrow  notation   Design  simple  multi-­‐step  synthesis  of  organic  products  by  using  the  organic  reactions  that  you  learn   Apply  what  was  learned,  and  reason  a  solution  for  related  problems   Appreciate  the  ubiquitous  and  ever-­‐present  relevance  of  organic  chemistry  to  the  world  around  us

Why  Learn  Organic  Chemistry?  

Organic  chemicals  are  everywhere  and  make  up  over  95%  of  the  more  than  91  million  (and  counting)  known  chemical   substances.  Natural  and  synthetic  organic  chemicals  are  in  the  clothes,  cars,  foods,  toys,  pharmaceuticals,  plastics,  and   most   other   consumer   goods   that   we   use   every   day.   Volatile   organic   chemicals   are   present   in   the   air   we   breathe.   A   foundation   in   organic   chemistry   fundamentals   is   necessary   to   understand   the   structure,   properties,   and   reactivity   of   drugs,   biochemicals,   and   environmental   chemicals,   which   impact   biological   metabolism,   nutrition,   disease,   health,   physiology,   neurology,   growth,   and   development.   An   understanding   of   organic   chemistry   can   help   us   make   rational   social  and  political  decisions  with  regard  to  chemicals  in  our  society.  

  Curious,  have  questions,  or  need  help?   Please  stop  by  my  office  during  office  hours  for  assistance  outside  of  class.  Ask  me  questions  during  laboratory.  Set  up   an   appointment   via   email,   if   my   office   hours   don’t   fit   your   schedule.   Email   me   your   chemistry   questions.   Start   a   discussion  on  our  D2L  site.    Form  a  study  group.    Get  a  tutor.    Free  tutoring  (individual  or  group)  is  also  available  through   Student   Services.   Call   or   stop   by   the   tutoring   office   in   Lyle   Hall   for   additional   information.

Chapters  15  &  16  (Spectroscopy)  will  be  discussed  in  the  laboratory.    


Exam  Dates:   Exam  1  (2/13);  Exam  2  (3/20);  Exam  3  (5/1);  Final  Exam  (5/8)   Note:  If  a  class  is  canceled  due  to  adverse  weather,  then  the  missed  exam  will  be  given  the  next  time  the  class   meets.  Check  the  Millersville  University  website  for  campus  closure  due  to  storms.    

Lecture  Attendance,  Exam  &  Quiz  Policy   You   are   responsible   for   all   notes,   discussions,   assignments   and   handouts   presented   in   each   class   (whether   you   are   absent   or   present).   You   are   expected   to   be   present   when   any   evaluation   (quiz,   test,   etc.)   is   given.   Absences   that   you   know   about   in   advance   may   be   excused.   Excused   absences   include   attendance   at   university   events   (athletic   and   educational),  military  duty,  bereavement,  critical  illness  in  the  family,  or  personal  illness  in  which  a  physician  indicates   that   you   were   too   ill   to   attend   class.   A   request   for   an   excused   absence   should   include   a   written   justification   of   the   reason  for  the  absence  and  be  signed  by  the  appropriate  individual  (coach,  faculty  member,  physician,  etc.).  Only  valid   excuses  will  be  accepted  to  make  up  any  missed  assignments.  Work  not  made  up  will  receive  a  grade  of  zero.  Departure   times  for  travel  before  university  breaks  are  not  a  valid  excuse  to  miss  class,  so  please  make  your  travel  arrangements   accordingly.   Most   exams   are   on   Friday   mornings.   Please   see   the   University   Attendance   Policy   for   more   information.    

Classroom  Etiquette    

Feel  free  to  ask  questions  in  lecture;  however,  socializing  and  chatting  off  topic  during  class  is  rude  and  unfair  to  those   students  interested  in  learning  and  participating.  If  you  persist  in  talking  during  class,  you  will  be  asked  to  leave.  Please   note  that  I  reserve  the  right  to  take  disruptive  behavior  such  as  habitual  tardiness,  frequent  or  excessive  talking  during   class,  cell  phone  disruptions,  or  leaving  before  class  is  over  into  account  when  determining  your  final  grade.    

Problem  Solving  

This  is  a  non-­‐mathematical  problem-­‐solving  course.  You  must  demonstrate  that  you  can  apply  what  you  have  learned  to   solve  new  problems.  To  pass  this  class  with  a  respectable  grade  (C,  B,  or  A)  most  students  work  problems  every  day  of   the  semester.  It  is  to  your  advantage  that  you  work  as  many  practice  problems  as  it  takes  until  a  concept  is  mastered,   even  though  most  problems  will  not  be  collected  or  graded.  There  is  a  strong,  direct  correlation  between  the  number  of   problems   worked   and   understood   to   exam   grades.   There   is   an   inverse   correlation   between   the   number   of   problems   worked  and  understood  to  the  perceived  difficulty  and  length  of  exams.           S.

  Academic  Honesty  &  Dishonesty  

Plagiarism  is  the  deliberate  or  even  accidental  representation  of  another’s  work  as  your  own  without  proper  reference.   Although   you   will   work   together   on   some   material   and   experiments,   this   does   not   mean   that   lab   reports   and   assignments   should   be   identical.   Each   participant   uses   the   collective   data   and   discussion   to   prepare   his   or   her   own   individual  report.  You  should  be  familiar  with  the  University  policy  on  academic  honesty  and  dishonesty  as  outlined  in   the  Student  Handbook  and  Academic  Honesty  and  Dishonesty  brochure;  the  content  applies  to  this  course.  If  you  are   caught,  you  will  be  removed  from  the  course,  assigned  an  F  for  the  course,  and  a  report  will  be  filed  with  the  associate   Provost  for  Academic  Programs  and  Services.   S.

Tips  for  Success:  

Solve  as  many  problems  as  possible.  Then  solve  more  problems.  Do  not  try  to  memorize  every  individual  thing  for  this   course.  It  will  not  work  well.  Instead,  try  to  focus  on  the  major  concepts,  and  examples,  and  develop  some  flexibility  in   the   application   of   those   concepts   to   new   examples.   Look   for   similarities   and   difference   in   the   course   content.   Make   connections   and   organize   new   information   based   on   your   understanding   of   old   information.   While   there   are   fundamental   principles,   concepts,   structures,   and   vocabulary   that   must   be   remembered   (memorized),   successful   completion  of  this  course  depends  upon  your  ability  to  problem  solve  by  utilizing  newly  acquired  information.       • Be  curious.     • Do  good  work.     • Problems  are  puzzles.     • Work  lots  of  problems.       • Then  do  more  problems!     • Learn  to  enjoy  problem  solving.     • Make  the  problem  solving  a  game.     • When  in  doubt,  draw  it  out.  Practice  drawing  structures.       • Actively  attend  lecture.  And,  take  good  notes  to  practice  quickly  drawing  correct  structures.     • Don’t   get   behind   in   this   class   due   to   the   pace   of   this   course.   This   is   not   the   type   of   class   that   you   can   effectively   cram  for.     • If  you  do  happen  to  cram  your  way  through  this  course  by  using  surface  learning  strategies,  then  how  will  you   ever   pass   Chemistry   232   next   semester   after   forgetting   fundamentals   that   you   did   not   commit   to   long-­‐term   memory?     • Do   all   of   the   required   readings   before   each   lecture.   Each   chapter   covered   is   required   reading.   Own   the   fact   that   you  are  responsible  for  all  material  in  each  chapter  of  the  textbook,  even  if  we  do  not  cover  it  in  lecture.     • Devote  time  to  this  class!  You  are  not  given  a  grade;  you  earn  your  grade.  You  cannot  realistically  expect  to  learn   even  the  basics  of  a  subject  by  spending  the  typical  1  to  2  hours  a  week  that  many  students  report  putting  into   some  courses.       • A  rule-­‐of  thumb  in  study  time  for  this  course  should  be  at  least  4  hours  for  each  1  hour  spent  in  class  per  week.       • To  obtain  a  passing  “C”  letter  grade,  I  recommend  at  least  12  hours  of  study  time  outside  of  class  per  week.       • Ask  questions!  There  is  no  such  thing  as  a  “dumb”  question.  Get  help  when  needed!!!  Don’t  put  it  off.     • Put  in  the  time  and  work  hard.     • Above  all,  have  fun  with  it!   S.

Lab   Attendance:   Attendance   at   each   laboratory   session   is   mandatory.   Failure   to   attend   each   and   every   laboratory   meeting  equals  failure  of  this  course.  Only  valid  excuses  will  be  accepted  in  order  to  make  up  labs.  In  the  event  of  an   anticipated   excused   absence,   arrangements   should   be   made   to   make   up   work   prior   to   the   absence.   Students   are   not   allowed   to   work   by   themselves   when   there   is   not   a   lab   in   session.   You   are   expected   to   have   read   the   procedure   thoroughly,  to  have  prepared  your  notebook  based  on  the  notebook  guidelines  for  this  course,  and  to  have  completed   the   weekly   pre-­‐laboratory   assignment   prior   to   each   lab.   SAFETY   IS   VERY   IMPORTANT   IN   THE   LABORATORY.   General   safety  guidelines  will  be  presented  in  the  laboratory  and  should  be  followed  at  all  times.  Specific  safety  precautions  for   each  experiment  will  be  covered  before  each  lab.  Failure  to  follow  safety  guidelines  is  reason  for  dismissal  from  a  lab   and   a   grade   of   zero   on   the   experiment.   Additional   laboratory   guidelines   including   notebooks   and   reports   are   covered   in   the  week  1  handouts.   S.
